My senior cat with cancer is losing weight and won't eat. Help!

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 12 years and 2 months old | 11 lbs

Our 12 1/2 year old cat Oscar, has been diagonost with kidney and lung cancer. He's hardly eating and appetite stimulant we tried hasn't worked at all. We have bought special foods like salmon mouse and a bone meal gel, that he ate the first night we tried but not since. Do you have any suggestions as Oscar seems very alert, just very lethargic and losing weight

Hello. I am so sorry that Oscar has such a sad diagnosis. Unfortunately, either one of these can cause a significant loss of appetite. The only two appetite stimulants we have for cats are mirtazapine & cyproheptadine, & even these are not miracle drugs. Some cats prefer foods that are warm, some prefer them when cold, so you can try this. Hand feeding may work a bit as well. You can also talk to your vet about the possibility of adding some anti-nausea medication like Cerenia. Hopefully, you can at least get Oscar to eat a little more for as long as possible. Good luck & thanks for contacting Petco Pet Education Center, formerly Petcoach.
